Using Iray controls

Keyboard Shortcuts

Once the Iray render engine is selected for the view port, gaining control over the speed of rendering, as well as well as quality of image is going to be key. We can do this via the min and max sample options, as well as by controlling the maximum amount of time allotted to the render, in values of seconds. Getting a balance between the two is our goal.

In other words, the minimum and maximum number…of samples per pixel that can be used…to produce the final image.…If we set the max value here to 15…and then orbit around in the 3D view,…then we see the view port update…as Iray tries to make use of the max number…of samples that we've made available to it.…However, we have a second-level quality control…that we need to take into consideration here.…

Meet Substance Designer, the node-based texturing tool for creating high-quality, procedural textures and materials. In this course, Joel Bradley walks through the workflow for creating an aged concrete substance, so you can become familiar with the basics of substances and the range of tools Substance Designer offers. When you are finished with the course, you'll have a complete substance package ready for handoff to a game engine such as Unreal or Unity, and the skills you need to continue creating your own materials with Substance Designer.

Topics include:

Creating a new substance graph

Importing resources

Setting up lighting

Generating maps

Creating material outputs

Using generator nodes to create surface detail

Using filters to create amps

Publishing a substance
